Complex carbohydrates, fat and insulin.
1. Our ancestors had a hormonal response to make the best use of sugar, found in honey or sweet berries on the rare occasion that it made an appearance in their diet. That turned on a hormone called insulin, which is a storage hormone. Insulin changes the blood’s chemistry and it leads to storage of fat for a rainy day, particularly around the stomach, but also in the arteries.
2. So, for some people who have an inheritable sensitivity to carbohydrates that causes a brisk insulin response, restricting carbohydrates is sometimes beneficial to reduce the rate of fat storage in the stomach and to reduce fat storage in the arteries in particular.
3. If your doctor has identified that you are producing too much insulin, they might recommend that you reduce simple carbohydrates by reducing complex carbohydrates.
4. Modern food processing has made available a large variety of simple and complex carbohydrates for consumption. So, under the advice and supervision of a physician, things like bread, pasta, potatoes, rice, cereal and fruit are sometimes kept to a minimum to maintain a diet, that is better for that individual’s heart health. This advice will depend on the individual, their metabolic make-up, their energy expenditure and dietary objectives.
